Spiking time-dependent plasticity leads to efficient coding and predictions

Latency reduction of postsynaptic spikes is a well-known effect of Spiking Time-Dependent Plasticity. We expand this notion for long postsynaptic spike trains, illustrating how it can be generalized to include inhibitory spike trains and some constraints on connectivity and neural activity. On the functional side, we show that a fixed presynaptic train induces early spike synchronization as well as a reduction in the number of postsynaptic spikes, thus improving neural codes. Finally, we show how this leads to predictions.
